Abstract
A process for enhancing the concentration of one component contained in a multi-component gas is disclosed which is particularly well-suited for enriching the oxygen content of air. The process is carried out by a series of adsorption and desorption stages using an Advanced Separation Device comprised of a plurality of adsorbent-filled chambers moving about a circular path in periodic fluid communication with a plurality of fixed feed and discharge ports. By using the Advanced Separation Device, it is possible to load the oxygen content of air onto the adsorbent which is then stripped by a second stream of air. This oxygen-enriched stream of air may then be divided so that the oxygen content of one stream may be adsorbed for subsequent removal by the other stream to produce a doubly-enriched stream.
